back to USB power testers

AT34 USB meter:




I got this to keep in my belt pouch for quick USB testing. It isn't as versatile as the J7C but it takes up
a lot less space in the crowded pouch. Only does USB-A, not USB-C.

It does count up energy used, but automatically resets it when powered off and back on again. When it powers
on, the energy used will flash about 10 seconds before clearing though, so you can catch it if you're paying
attention to it, but you'll just have to keep track of it if you need to add up multiple sessions.
